Alumina porous ceramic with controlled pore size distribution was produced and its potential as a random laser host is investigated. Bi-chromatic random laser was observed from rhodamine B infiltrated ceramic when excited by 532 nm pulsed laser. Two random laser regimes were characterized and associated with the excitation of monomers and dimers. The results show that this class of material is very promising for the development of low-cost solid state random lasers.
